Part: Part 7-2 (2010; Edition 2)

Links: #1432 Resv required to be set before configuring URCB

Page: 117



Category: Issue for edition 2 of this part


There is nothing specified if a Server device shall reset an reserved URCB after the association got lost/were aborted/released.


The server shall set Resv to FALSE after association lost/release/abort to avoid a blocked URCB. If a non-persistent dataset were used the UCRB needs anyhow a reconfiguration.

For URCB not reserved by SCL, The server shall set Resv to FALSE after association lost/release/abort.

See TISSUE 1432 also. SCL issues are addressed there.
28 Oct 15 Ballot Period
A lost client does not automatically mean that the client releases the URCB. Having a link to a non persistent data set is a special case. The reset may only be appropriate if Resv has been set with communication services directly or indirectly via RptEna, but even then not always, if the data set is preconfigured or persistently defined. If it has been reserved via SCD file, it must stay reserved. 26 Aug 15 Discussion (red)

as a non-persistent data-set will be deleted at association lost, the datSet attribute will automatically be emptied too.
